I am of the believe that not all religious people hold this attitude towards their children. As young people tend not to have much experience about the world, some parents may believe that inculcating religious principles in their kids' minds will help them to protect themselves from harm.

There are researchers who agree that extended periods of contact with a specific social group will affect the personality of the individual, influencing him to shape his attitude towards what's common to the group he was accepted in, regardless of his previous take on the value of the behavior itself.

For the most part, the internet carries a skeptic ideology - for obvious reasons, since anonymity and detachment are features of a reasonable number of interactions on the internet - that refers to "logic" as a use of the scientific method to refer to theories, ideologies, dogmas or statements as plausible. Obviously, religion in general falls, more often than not, in the negative side of this assessment, mainly because of the blatant examples of people - not the actual concepts in which the religion is based on - not doing what they hold as sacred. So the internet connects the failure of people - natural, since people make mistakes, regardless of their beliefs - with the failure of the belief itself. If a Christian practices fornication, that means that the religion is bad.

"I know that after my going away oppressive wolves will enter in among you and will not treat the flock with tenderness, and from among you yourselves men will rise and speak twisted things to draw away the disciples after themselves." (Acts 20:29, 30)

For some religious people, however, this concept proposes a spiritual challenge, not an emotional one. Someone who is not religious doesn't consider any other type of danger, besides emotional and physical ones. A religious person consider any mentality, propaganda or intellectual framework that bases its ideology on statements that contradict religious principles, a danger, as important, if not more, as physical and emotional ones.

Do not be misled. Bad associations spoil useful habits. Come to your senses in a righteous way and do not practice sin, for some have no knowledge of God. I am speaking to move you to shame. (1 Corinthians 15:33, 34)

Here is an insight on the notions of a religious parent, for instance: They are seeing their child walk into an abyss - even if the son himself or other people are not seeing it -. From everyone else, sometimes including the child, there is no abyss. There is no danger. Except that for a religious person, there is and a big one. Free-will notwithstanding, some Christians will most likely attempt to advise their son or daughter against it, knowing that the decision is theirs, when they become adults, and ultimately, the consequences for that decision as well.

"So, then, each of us will render an account for himself to God." (Romans 14:12)

"For each one will carry his own load." (Galatians 6:5)

Obviously, from the perspective of someone who does not share the same point of view and even less the urgency of its danger - most of the internet -, they'll see no reason to believe that they will fall down into an abyss. Also, since millennials are starting to believe that there is no danger - because that's the most propagated idea among young people -, they will gradually, but steadily, get less and less involved with both the premise of any dogma and also its behavioral demands.

Whether there is danger or not, that's belief. Most people who grew up with those beliefs have never been intellectual challenged about them. Nowadays a 17 year-old who grew up hearing about creation, a loving God and a purpose for his existence, will go to school and learn that there is no evidence for this claim and that, actually, scientists, who use a strict method of solving problems and finding the truth about our universe, state otherwise, that there was no intelligent design, there is nothing supernatural, including the most common definitions of God and also that our lives are ephemeral and meaningless in terms of time and happiness. Our condition is natural and simple. We are alive now and we will not be eventually. Once we are not it's the end of everything for that creature. There is absolutely no hope for more time.

Most of the internet will advise this kid against this belief. It'll provide reasoning, critical thinking, logic and skepticism as a better option. But the internet does not care about one thing that the parents do: love. The kid's well being for anyone here on Reddit is simply irrelevant. Whether or not he's happy is his own path to find. Millennials have chosen the internet's argument, over their parents. Eventually, religion will be a detail of human society, and not a major participants of its most memorable, yet regrettable moments.

Only the future can tell if it will have been a wise decision or not.
